In the stable hard shell you can then create an in-ear headphones, there is also an "network specialist", in which you can insert a memory card, for example.
The zipper is smooth and overall makes the box a sophisticated look. Unlike other reviews here, I could make out no smell and the case also looks exactly like the pictures.
My problem is, however, that I use clip headphones (which are plugged into the ears) and go here not as good pure. If arg gequetsch and that I wanted them but then do not.
But the description does say clearly "earplugs". So that's why no devaluation, I just wanted to mention.
The cases have found at least all their use in me and I am very happy for the money.
